Its role in pelvic collections remains limited to patients who fail imaging-guided drainage and who are unsuitable for surgery. The positive data from Puri et al.9 are encouraging, and it may become more widely accepted if it is validated by other prospective data. Natural orifice transluminal endoscopic surgery is currently a subject of scientific research.15 It utilizes a similar transluminal approach for surgical procedures and may result in development of accessories
that can facilitate the process of EUS-guided drainage and improve procedural efficacy and safety. “
“The role of serum quantitative hepatitis B surface antigen (qHBsAg) in identifying hepatitis B virus (HBV) carriers with significant fibrosis is unknown. This study aims to evaluate the diagnostic PLX4032 order value of qHBsAg for hepatic fibrosis in hepatitis B e antigen (HBeAg)-positive HBV carriers. Consecutive Selleckchem Dabrafenib biopsy-proven HBeAg-positive HBV carriers were prospectively recruited in our center from 2009 to 2011 and were randomly divided into training
and validation set. Area under receiver-operator curve (AUC) was used to determine the diagnostic accuracy of simple tests for significant fibrosis (Scheuer stage, F ≥ 2). Overall, a total of 197 eligible patients (median age 31 years; 149 males) were enrolled. The median qHBsAg was 4.20 (log10 IU/mL). Significant fibrosis was confirmed in 112 (56.9%) patients. By logistical regression analysis, qHBsAg and γ-glutamyl transpeptidase were 上海皓元医药股份有限公司 identified as predictors for significant fibrosis in training set (n = 124). Thus, qHBsAg index and γ-glutamyl transpeptidase to qHBsAg ratio (GqHBsR) were selected for the subsequent analysis. In the training set, an AUC of 0.762, 0.826, 0.749, and 0.771 was observed for qHBsAg index, GqHBsR, FIB-4, and aspartate aminotransferase to platelet ratio index, respectively (all P < 0.05).
GqHBsR yielded a higher AUC than aspartate aminotransferase to platelet ratio index and FIB-4 (both P < 0.05). Using the optimal cut-off of 7.78, GqHBsR showed a sensitivity of 78.9% and a specificity of 73.6%. About 80% of liver biopsy could be avoided in the entire cohort. Serum qHBsAg-based simple tests, especially GqHBsR, can accurately and specifically identify significant fibrosis in treatment-naïve HBeAg-positive HBV carriers. "
“Barrett’s esophagus (BE) is a premalignant condition to esophageal adenocarcinoma. It is currently not clear whether cigarette smoking increases the risk of developing BE, and no meta-analysis has been performed on the topic. We conducted a systematic review and meta-analysis, providing a quantitative estimate of the increased risk of BE associated with cigarette smoking, to help clarify whether a relationship exists between smoking and BE. Four electronic databases (Medline, PubMed, Embase, and Current Contents Connect) were searched to May 17, 2013, for observational studies of BE patients.
